Re: How to design a monotube steam separator?

"Do you think your steam is very dry already? (In your "machine gun" monotube) I am asking because I was thinking of placing a cyclone separator inside the top of the flask. It'll definitely not hurt, but if the tangential inlet already works out fine, I wouldn't need to braze one together." The mon...

Re: How to design a monotube steam separator?

Large plant practice dictates a steam/water inlet, tangential to the vertical main vessel, about half way between top and bottom. Vessel steam upflow velocity 3 feet per second (about 1 Meter per second), with minimum 1.5 main vessel diameters above for steam outlet, plus 1.5 vessel diameters below ...

Re: American Walking Beam Engine

Not at all "off topic" Almost all typical steam engines used harmonic motion for valve gears, usually with an eccentric producing continuous motion, mathematically a complex combination of Sine waves. Usually with slide valves or piston valves, with ports opened/closed during the valve continuous mo...

Re: American Walking Beam Engine

Mike, the owner of this engine will soon be looking for a suitable hull, probably a convert-able sailboat hull in the 60 - 90 foot range, in the New England area, as building a new hull would be far more expensive. Ramon, the walking beam sidewheel engines of the USA were all very similar, and I bas...

Re: Oil inside the condenser

Oil separation in exhaust steam can be very effective, assuming the design of the separating device is correct. However these devices also separate water (exhaust steam wetness) from the exhaust stream, which is significant in our steam launches. IFF the exhaust steam is superheated, then effective ...

Re: American Walking Beam Engine

Here is a picture of a somewhat larger, and far more authentic, walking beam engine in the building process, June 2019. It is about 33% of original size, so I guess it is a small scale model of the original.

Re: I'd need help with my lathe v-belt drive

Ordinary V-belts work very well with low friction. My Atlas lathe, 12 x 36, built about 70 years ago uses a typical 1/2 inch wide V-belt with a 3/4 horsepower motor. I have been using this lathe for 25 years without any belt problems, and have never changed the belt. Maybe there is heavy friction in...
